Antibodies

Antibodies are proteins
synthesized and secreted by B cells that
bind to antigens. Most antigens are macromolecules: proteins, polysaccharides, even DNA and RNA.
The interaction occurs: ...

Monoclonal antibodies (mAb) are antibodies that are identical because they were produced by one type of immune cell, all clones of a single parent cell.

Antibodies specific for the different neoepitopes generated by such cleavage events provide powerful tools with which to analyse these processes.

Antibodies bind to specific antigens in a lock-and-key fashion, forming an antigen-antibody complex. Antibodies are a type of protein molecule known as immunoglobulins. There are five classes of immunoglobulins: IgG, IgA, IgD, IgE, and IgM.

Antibodies are the most widely used binding ligands in research, and recent molecular diversity techniques (e.g. phage display) permit the generation of antibody fragments, comprising the binding domain alone, without the use of animals.

Antibodies can also be used to purify proteins. Antibodies to a protein are generated and are often then coupled to "beads".

A blood protein that is produced in response to and counteracts an antigen. Antibodies are produced in response to disease and help the body fight against the particular disease. In this way, antibodies help the body develop an immunity to disease.
